Abstract
Abstract A flexible key case is provided which contains an upper end portion, a lower end portion with an opening, and a sidewall extending between the upper and lower end portions. The sidewall has a longitudinal slot and defines a cavity that is accessible through the slot and through the opening of the lower end portion. The key case includes a key ring and means, connected to the key ring, for raising the key ring into the cavity adjacent the upper end portion and lowering the key ring from the cavity through the opening of the lower end portion. The key case holds a plurality of keys in a neat, compact package that shields the keys from contact with a pocket or purse and minimizes jingling. Keys are easily added or removed from the key case and the key case is simple to operate.
